摘要：The routing protocols in wireless sensor network works on the formation of path from the sensor node tobase station in the effort to consume minimum energy possible. The energy consumption is reduced in case ofhierarchical protocols by forming a hierarchy from the sensor node to the base station with the help of cluster heads.The cluster head formation process effect the efficiency of the network. The network performance is directly linkedwith the cluster head number, cluster size and the energy of the nodes which form the cluster head. The cluster headformation process in case of the traditional routing protocols depends on the selection probability for the cluster head.In case of networks having the heterogeneous environments, the network adopts the policy of applying the differentelection probability for the different type of nodes. This seems to have the disadvantage that it doesn’t take theadvantage of these special types of nodes to the fullest. Because if the node is having higher energy in an area it shouldform the cluster instead of any other node forming the cluster. This is done in the proposed algorithm by adoptingsingle criteria for the election of cluster head i.e. the fitness function. The fitness function applied here is modified insuch a way to take in to consideration the remaining energy of the node in that area for the selection of cluster head. Asa result of change in the election process and adoption of new technique in new form, the network performanceincreases to a large extent making it more energy efficient and increasing its number of rounds.
